Is the problem easily reproducible? Debug logs could really help to get where the problem happened.

There seems to be a problem with unbalanced ref counts in MMCallbackInfo. We could try to minimize the problem just checking the refcount to be > 0 when calling mm_callback_info_unref(), but the proper fix is to avoid that additional call to unref(). As said before, debug logs could really help to check where exactly (in which MMCallbackInfo) the issue is happening.

Status changed to 'Confirmed' because the bug affects multiple users.

Is this reproducible, we haven't heard back from you yet?

Thank you for your valuable efforts.

Received this bug today in Ubuntu 13.04 after login without interaction. As far as I remember I received this bug sometimes in Ubuntu 12.10 too. I have a Lenovo T500 with F3507g WWAN-Module which stays always disabled in network manager because i don't need it. I guess that it appeared after enabling that hw module in bios for potential use.

I received this bug sometimes in Ubuntu 12.04 LTS too.
